DDZ43S-7 Discrete Semiconductor Products

Diodes - Zener - Single

Diodes are electrical components that allow current to flow in only one direction. A single diode, or Zener diode, is a diode designed to allow a reverse current in a specific voltage range. Zener diodes are particularly useful in power supplies, where the flow of current must be strictly controlled and regulated. The DDZ43S-7 is a single diode with a specific application field and working principles.

DDZ43S-7 Application Field

DDZ43S-7 diodes are commonly used as protective components and regulators in power supplies. They are also used to prevent overvoltage from affecting downstream components in communications systems, semiconductors, transistors, and amplifiers. DDZ43S-7 diodes can also be used for frequency- and power-sensitive applications where precise voltage regulation and current stability is required, such as those found in electronic & electrical medical equipment, mainframe computer systems, and automated machinery control systems.

DDZ43S-7 Working Principle

A single diode or Zener diode, has two elements: an anode, which is the positive terminal; and a cathode, which is the negative terminal. When the diode is exposed to a voltage that is greater than its reverse breakdown voltage, it rapidly switches from blocking to conducting current, providing a constant voltage output, regardless of the input voltage. The stored information will protect the components downstream by allowing the diode to absorb the excessive voltage.

In the DDZ43S-7, the reverse breakdown voltage is 6.2 Volts, making it appropriate for a number of applications that require control and regulation of voltages. The maximum forward voltage drop of this diode is .07 Volts, resulting in a relatively low power loss. This is an advantage for applications that require high precision.

Conclusion

The DDZ43S-7 single diode is a useful and versatile component that allows for precise voltage regulation and current stability. It is frequently used to protect downstream electrical components and can be found in many different applications, from medical and scientific equipment to mainframe computers and automated machinery.
